Greetings, a beginner Splunk administrator here.
So I have the case where within my network there are two isolated network zones. One such that could be classified as intranet-oriented or less fortified one, and the other highly fortified with servers holding records needed for eventual collection.
Communication between them occurs through the firewall. Intranet zone holds the crucial indexer.
How could I collect logs from the fortified zone over the firewall between these zones with Splunk forwarder while not opening too many network ports or compromising the network in any way.
From your experience, I'd like to hear several ways in approaching this.
